TAMFING TOOL.

Application filed August 3, 1921.

To all whom t may concern:

Be it known that I, KNOX TAYLOR, a citi- Zen of the United States,residing at High Bridge, in the county of Hunterdon and State of NewJersey, have. invented certain new and useful Improvements in TampingTools, of. which the following is a specifica to provide a tamping toolwhereof at least the wearing portion of the head shall be constructed ofmanganese steel, which is remarkable for its toughness, hardness andenduring qualities. In practicing the invention, the head, or itswearing or impact portion, may be integral with the remaining structure,or it may be detachable, or detachable and reversible. Moreover, it isotherwise so constructed that it may be readily cleared of any ballastmateria-l which it may trap, and re-dressed, as by grinding, ifnecessary or desirable.

The nature, characteristic features` and scope of the invention, willmore readily be understood from the following description and claims,reference being had to the accompanying drawing, forming a part thereof,'wherein- Fig. 1 is a perspective view of the tamping tool embodyingmyinvention.

Fig. 9 is an end view thereof; and- Fig. 10 is a similar view of thesame redressed after service.

Referring to Figs. 1 and`2, a tamping tool is indicated, the head 5 ofwhich is preferably constructed of manganese steel. The impact portionof the head is cupped or concaved, as at 6, to facilitate grinding, whennecessary, but mainly to engage the ballast material. There are endslots 7 and laterally opening slots 8, which when present are useful inejecting any ballast material which may stick in the cupped portion 6.

In the modification, Figs. 3 to 5, the impact or wearing portion of thehead is cupped as at 9, the cupped area merging with a relatively deepslot 10 extending the length of the head and open at both ends. Asidefrom its utility in ejecting trapped ballast material, the full lengthslot 10 is useful to temporarily take care of metal peened from thesurface, and it is furthe-r useful in that it simplifies redressing ofthe impact surfaces as by grinding or otherwise.

The head may be solid with the shaft, or it may be constructed with adetachable wearing or impact element 11, having an interlocking fit suchas shown, for example at l2.

I may also, if desired, provide a reversible impact element such as, forexample, shown in Fig. 7, which illustrates a .double member soconstructed and arranged that when one face 13 is worn, it may bereversed to present the other face.

Figs. 8, 9, and 10 illustrate a tamping head having a full length slot14 which eX- tends to within a comparatively short distance of theshaft, and is cupped as at 15. In service, the wing members or sidewalls 16, have a tendency to spread, as indicated in dotted lines inFig. 10.

The head is then re-dressed, as by grinding, so as to insure uniformlystraight outer walls. The effect of the spreading is to impart a flare17 to the slot as clearly shown in Fig. 10 and this condition ismanifestly useful in holding and advancing the ballast 2.
